Loch Oich: The High Point of the Caledonian Canal
Nestled within the rugged beauty of the Highlands of Scotland, Loch Oich (known in Scottish Gaelic as Loch Obhaich) is a stunning freshwater loch that serves as a vital link in the region's geography. Situated in the Great Glen, this narrow body of water is most notable for being the highest point of the Caledonian Canal, a feat of engineering that connects the east and west coasts of Scotland.
Positioned between the world-famous Loch Ness to the northeast and Loch Lochy to the southwest, Loch Oich is a serene landscape shaped by both nature and human ingenuity. It is fed from the west by the River Garry, which flows from Loch Garry, and it eventually feeds the River Oich from its northern end.

Geography and Engineering
Loch Oich is characterized by its narrow profile and significant elevation, with a surface elevation of 32 meters. To ensure the loch could function as a navigable channel for the Caledonian Canal, the renowned engineer Thomas Telford artificially raised the water level by several feet.
This modification allowed vessels to traverse the Great Glen more efficiently, utilizing the Laggan locks to transition between Loch Oich and Loch Lochy.

Biodiversity and Wildlife
The ecosystem of Loch Oich is remarkably rich, supporting a diverse array of mammals, birds, reptiles, amphibians, and fish. One of the most significant biological events occurs every autumn, when Atlantic salmon (Salmo salar) migrate from the sea. These fish utilize Loch Oich, along with Loch Lochy and Loch Ness, as essential spawning nests to ensure the survival of the next generation.
The Well of the Seven Heads
Beyond its natural beauty, the banks of Loch Oich hold a dark and fascinating piece of Scottish history. Located beside the A82 road is a tall, needle-like monument known as the Well of the Seven Heads. Erected in 1812 by Alexander Ranaldson Macdonell, the monument commemorates the Keppoch murders (Murt na Ceapaich).
The monument is topped with a sculpture depicting a hand holding a dagger and seven severed heads. An inscription in Gaelic, English, French, and Latin describes the "ample and summary vengence" ordered by the Lord MacDonnell and Aross against those who murdered the Keppoch family. According to the account, the heads of the seven perpetrators were severed with a knife, washed in a nearby burn (a small stream), and presented to the MacDonnell chieftain at Invergarry Castle.
While the monument originally stood in a different spot, it was moved a few yards in 1930 during the reconstruction of the road.
